Clone Ubuntu to new vm in PVE, result with duplicated IP from DHCP

95

This is a known issue and no solution, just a workaround to as follow.

To work around this issue, VMware recommends to prepare a VM template running an Ubuntu Guest OS with an empty /etc/machine-id.
Clone your VM template to a new VM.
Power on the new VM and run these commands inside the Linux Guest OS:

echo -n > /etc/machine-id
rm /var/lib/dbus/machine-id
ln -s /etc/machine-id /var/lib/dbus/machine-id
 
Re-clone the new VM to a new VM template.
Alternatively, prepare a VM template explicitly setting the dhcp client identifier to mac.

Example 1: set the “dhcp-identifier: mac” in the /etc/netplan/*.yaml file as below:

network:
  version: 2
  renderer: networkd
  ethernets:
    default:
      match:
        name: e*
      dhcp4: yes
      dhcp-identifier: mac

Example 2: set the “ClientIdentifier=mac” in the /etc/systemd/network/default.network file.
